Introduction
Welcome to the Nx12
The Telos Nx12 combines a 12-line selector and 4 hybrids with advanced signal processing to
deliver all you need for your on-air phones. The four hybrids make it ideal for programming
where multiple callers are aired simultaneously. It also has the flexibility to serve two studios
with two hybrids for each.
At the heart of any broadcast telephone system are the hybrids and associated signal processing.
Based on the latest Telos technology, the Nx12 includes the very best broadcast hybrids avail-
able.
Depending on the version ordered, the Nx12 can use six ISDN (Integrated Services Digital
Network) BRI circuits (with 2 channels per circuit) or 12 analog lines, or a 50/50 mixture of the
two types.
The Nx12 has support for up to eight Telos third-generation control surfaces such as our Call
Controller and Desktop Director. It also supports control via IP/Ethernet.
Studio equipment can connect with analog, AES3, or Livewire IP audio.
